Transport in Sri Lanka is based on its road network, which is centred on the country's commercial capital Colombo. A rail network handles a portion of Sri Lanka's transport needs. There are navigable waterways, harbours and three international airports: in Katunayake, 35 kilometres (22 mi) north of Colombo, in Hambantota, and in Jaffna.

The Sri Lanka Transport Board (formerly: Ceylon Transport Board, CTB) is a bus service provider in Sri Lanka.
